To all whom it may concern:

Be it known that I, GEORGE M. CARNEs, a citizen of the United States,and resident of Rochester, in the county of Monroe and State of NewYork, have invented certain Improvements in Shoe-Shaping Machines, ofwhich the following description, in connection with the accompanyingdrawings, is a specification, like reference characters on the drawingsindicating like parts in the several figures,

This invention relates to shoe shaping machines and is embodied in amachine for shaping the shoe at the juncture of the upper and the soleand particularly for shaping the shoe at and adjacent to the randcrease.

The object of the invention is to give to the shoe stock a uniformappearance along the length of the crease. In making shoes the upper islasted over the edge of the botton face of the innersole and crimped asit is bent inwardly to position for being secured. This lastingoperation, particularly about the heel portion of the shoe where theupper materials include a heel stiffener, leaves an edge contour for theshoe bottom which is more or less irregular. Upon the shoe thus preparedthe sole is attached and trimmed down to a contour and sizeapproximating closely to that of the adjacent portion of a lasted shoe.Between the upper and the sole thus ap lied there is a narrow crease andbecause 0 the narrowness of this crease slight irregularities in thecontour of the upper or the sole are conspicuous and detract from theappearance of the finished shoe.

More specifically stated, it is an object of this invention to shape bybeating or rubbing pressure the faces of the shoe which constitute thewalls of the rand crease and also to shape the portions of the upper andthe sole adjacent to the walls of the crease so as to give to thisportion of the shoe a regular and smooth appearance.

Another condition. which develops in the making of a shoe is that theadjacent faces of the sole and the bottom of the lasted shoe frequentlyare found to be slightly out of parallelism along the edge of the shoebot tom so that when said faces are forced t0- later in attaching theheel, the rand crease between these faces will be of varying depths atdifferent points because of this lack of exact parallelism or evennessin the contacting faces.

It is an object of this invention to improve the appearance of shoes byovercoming this irregularity in the depth and shape of the rand crease.

To these ends, an important feature of the invention consists in shapingtools which may be beating or rubbing instrumentalities, or both beatingand rubbing devices, for treating the upper at and adjacent to the randcrease of the shoe to remove such irregularities in contour as thoseabove mentioned. Advantageously the shaping tools may be heatersarranged to strike light rapid blows against the face of the work andthen to rub or roll, or both rub and roll, over the surface adjacent tothe point of impact. As shown, these beating devices are rollers havingappropriately shaped peripheries to conform to the vertical curvature ofthe side of the shoe and are mounted upon arms of a rotary carrier, thearrangement being suchthat the arms project the rollers outwardly bycentrifugal force as the carrier turns and thereby causes the heaters tooccupy outermost positions from which they will yield againstcentrifugal force after striking the work. Conveniently means which isadjustable is provided for limiting the outward movement of the arms andthe construction herein shown of such limiting means and provision foradjusting it possesses practical merit.

A further feature of this invention c0nsists in the provision ofupperbeating means which may be the means above described or other meanssuitable for the purpose and a cooperating beater of appropriateconstruction for shaping and hardening the g of the sole around the heelseat and adapted to do its work at the same time that the upper is beingbeaten. This combination is embodiedher-ein in a rotary sole edgebeating block having a transversely curved beating face and this blockserves as the rotary carrier for the upper beating devices abovedescribed.

A further feature of the invention consis s in providing, in s h combinti n that last aboy e described, means for accurately guiding the shoeto insure its presentation in such a position that the upper beatingdevices shall treat the upper over the desired area and the sole edgeshaping device shall properly act upon the sole without liability ofeither of said devices engaging and injuriously effecting the portion ofthe shoe which the other device alone is intended to treat. As shownthis guiding means is a device adapted to engage the shoe in the randcrease. Preferably this rand crease guide is formed and arranged toserve as a molding or shaping tool for imparting to the rand creasearound the heel a uniform shape and particularly a uniform width. In thecombination described the devices which treat the upper, above thecrease, and the edge of the sole, below the crease, cooperate with thecrease guide by forcing the stock against the guide so that said threedevices form a molding apparatus in which the crease guide is the innermem ber against which the upper stock and the sole stock, respectivelyare forced in order to produce a shaped rand crease. This action of theupper engaging and sole engaging devices, and particularly that of theformer device, beats and forces the stock inwardly with relation to theedge of the shoe bottom and tends to close the rand crease as to depthas well as width.

The above mentioned features of the invention and others which willappear from the following description will be more definitely pointedout in the claims.

Figure 1 of the drawings shows a front elevation of a shoe shapingmachine embodying'this invention; Fig. 2 is a side elevation, and Fig. 3is a section on the line 33 of Fig. 1 and shows a shoe in position to betreated.

The machine comprises a standard 2 in which a tool shaft 4 is mounted ata convenient elevation for the operator to present the shoe to thetools. The shaft 4 is driven from a pulley shaft 5 and on its forwardlyprojecting portion has a flange 6 against which a short threaded sleeveor nut 8 has bearing. This nut forms a sup port for the hub of a rotaryblock 10 and clamps said hub endwise against the serrated end face ofthe shaft, as shown most clearly in Fig. 2, whereby the block iscompelled to rotate with the shaft but may be adjusted rotativelythereon when the nut is loosened.

The rotary block 10 has a peripheral face 12 shaped to engage the edgeface of a shoe sole, said face being shown as interrupted by transversegrooves which are inclined to the axis of rotation of the block, andcause the block to have a, slight beating as well as a rubbing'actionupon the sole edge. The block 10 has eccentri a y l a ed Screw threadedrecesses parallel with its axis of rotation in which are mounted studs20 the inner ends of which are threaded and the outer portions of whichare smooth with a flange at the outer end, as shown in the sectionalview, Fig. 3. .Upon each of these studs 20, of which there are two, ismounted the hub 22 of an arm 24, said arm having at its free end a studextending toward the block 12 and upon which a beater 25 is mounted. Theheater is shown as a roll turning freely 011 the stud and having itsperiphery shaped in substantial accordance with the vertical curvatureof the side of the shoe just above the rand crease. Each of the arms 24has an inwardly projecting heel 27 which is adapted to engage theelliptical end 28 of the shaft 4 or, it may be,

of a stud rigidly attached to the shaft, to

limit the turning movement of the arm in the direction to project thebeater 25 outwardly upon the axis of rotation. By loosening the nut Sthe block 10 with the parts carried by it can be adjusted with relationto the stop 28 to permit more or less projection of the heaters and theblock 10 can then be locked in its adjusted position by the nut and theserrations on the end face of the shaft. The studs 20 are held securelyin place in the block 10 and thereby safely confine the hub of the arm22 between the block and the flange of the stud and confine the beater25 between the arm and the adjacent face of the block by forming thethreaded portion of each stud 20 as a split sleeve, the bore of which istapered. A bolt 29 is employed to draw a taper nut into the splitport-ion of the stud thereby locking it against turning.

The rand crease shaping device 30 is located between the beaters 25 andthe face 7 of the block 10 which operates against the edge of the shoesole. The rand crease shaping device is here shown as formed by a fin orflange projecting from the rotary block 10 at its front edge.

In the use of the machine the shoe may be presented as in Fig. 3 tocause the upper materials above the rand crease to be beaten by thecentrifugal beaters 25 and to cause the edge of the sole to be beaten bythe face 12 of the block 10. This action of the rapidly striking heaters25 shapes the upper materials closely to the contour of the last andleaves the outer surface of the shoe above the rand crease smooth andregular. The action of the beaters 25 also forces the upper at the edgeof the shoe bottom into the rand crease and tends to close the randcrease. The action of the sole edge beater 12 compacts, hardens andsmooths the surface of the sole edge and also tends to force the solestock into the rand crease. The rand crease shaping device 30 standsconstantly in. the crease between the pointwhere the upper is beingbeaten on one side of the crease and the point where" the sole is beingbeaten on the other side of the crease and produces, in Combination withsaid heaters, a rand crease of definite shape and of uniform width anddepth all the way around the heel. The heaters and the shaping devicethus cooperate to mold the shoe stock at and upon opposite sides of therand crease to determine the shape and size of the crease and thecontour of the surfaces of the sole and upper adjacent to the crease.
